AbstractThe term ‘stimulant’ refers to a class of drugs that increase psychophysiological arousal. From the viewpoint of prevention, it is more useful to look primarily at the social consequences and functions of stimulants. Every society has a documented use of stimulants. When planning interventions the dynamics of use must be placed in the foreground. Stimulant epidemics, like problematic stimulant users, have a natural tendency to burn themselves out. Different types of stimulants may differ in their origins, but their epidemiological consequences and use functions tend to be similar. Implications for prevention can be drawn from the characteristics of stimulant use epidemics. Users at risk for socially unacceptable patterns should be targeted for prevention efforts. Mass media campaigns that single out stimulants should be avoided. Much of the harm associated with stimulants is a consequence of life‐styles characterized by polydrug use and unhealthy practices. Prevention should be timed to the appropriate period of the epidemic. Interventions useful at period I will not work at period 2. The recommendations of the WHO Advisory Group on the Adverse Effects of Cocaine and Coca provide a good model for primary, secondary and tertiary prevention for all forms of stimulant misuse. Stimulant prevention must be creative in finding ways of encouraging the movements of the drug to the periphery of users
